The goal of the projects throughout this semester is to implement a “prototype” database system application for a eCommerce social-network system called UCOnline where users can explore information about books/music/software, rate your purchase, identify purchase price and see ratings of their friends.The project will require your teams (see attached for group member breakout) to complete the assignment. Below you will find the ERD deliverable requirements. Each assignment has a specific grading rubric (scheme) associated with the assignment.BUSINESS REQUIREMENTS ACROSS ALL ASSIGNMENTSYou will work with book/music/media information, user information, ratings of books, and users’ social networkEach book has an id, title, publication date, publisher, ISBN, functional category, page count, price (publisher), and product descriptionThere are 3 categories of book: fiction, non-fiction, and specialtyThere are 2 categories of music: digital and media-basedAn author can write one or more books.A musician can be a solo artist, part of a group, or bothAn author can also be associated with one or more publishers.A musician/group/act can be associated with one or more music housesAn author’s book can have one or more editions.A song and or album can have more than one version/edition (i.e. EP, LP, CD, DVD etc)A publisher can have many authors and many books.A record company can have many artists associated and many albums associated with it.A record company can also be the publishing company (i.e. self-publishing)Many ISBNs can also be associated with a given publisher but only one ISBN per form of medium (ie the ISBN is the PK no matter what).An author can write many books.An artist can write many songs, albums etc.UCOnline needs to keep track of user ratings for each item sold in the online store (e.g., 1-5 and 1 for ‘Dislike’, to 5, for ‘Awesome!’).A particular user rates a particular item at a given time.A user CANNOT rate the same multiple times unless there are multiple editions of the item. Each edition can be rated separately.Each user who submits a rating will be identified by a unique id and has a name, gender, age, and location. Nothing is anonymous.There is also a social network between users. Users can send communication requests (i.e. instant messages/emails) to other users. Such requests can be accepted or ignored. Once accepted, the two users are considered ‘book buddies.’ If ignored, the user can send the request again. We want to add a store when the requests were sent (timestamp), the result of the requests and when the request was answered (timestamp).Using the use case list above, you are to submit the following as your final project as a GROUP.(a) Working ERD Diagram(b) Explanation of the relationships used in the ERD Diagram (text-based summary)(c) URL of a WORKING database that maps your database solution. It should be a working prototype. I strongly encourage you testing this and using this as an opportunity. There are many free offers for AWS, Azure, GCP available - especially for students.Using the use case list above, you are to submit the following as your final project as a GROUP.(a) Working ERD Diagram(b) Explanation of the relationships used in the ERD Diagram (text-based summary)(c) URL of a WORKING database that maps your database solution.

Learning Outcomes:1) Manage database instances and database storage2) Work with Distributed Databases3) Manage database network (client/ server) connections using Database Net ServicesAssignment Objective:The objective is to enable the student to work on a relational database server and involve in creating, securing and maintaining of objects needed for databases. Hence, student’s ability to think and engage with the topic is tested. Task 1 –SQL/XML is an extension to the SQL standard that specifies SQL-based extensions for using XML in conjunction with SQL,a. Explore XMLElement() to Generate Nested XML Document with appropriate code and explanation.b. Explore XMLElement() to Generate XML document containing an elements with its attribute on some specific condition with appropriate code and explanation.Note:- Please ensure that the names of all table, elements, attributes must have my student ID at the end like Order_09F4972.Task 2 –Write a detailed reflection on “Comparison of NoSQL and SQL Databases in the Cloud”. You can include some more resources for building up your reflection. The web link to a research paper “Comparison of NoSQL and SQL Databases in the Cloud” is given in the college Moodle web page (hyperlink of the research article is given below):https://vulms.vu.edu.pk/Courses/BIT703/Downloads/HammesEtal.pdfNote:- The given research paper is for your reference only and your answer should not be limited to this paper only. You may refer various other resources and provided references for the same. Do not simply copy and paste the information from the research papers or any other resource.- The solution for the task-3 must be given in your own words with relevant examples not exceeding 500 words.Task 3 –“A flashback query is used to retrieve the committed data as it was at a past point in time”. Demonstrate this feature with proper code and explanation in your own words not exceeding 500 words.*** In Task 1 Please ensure that the names of all table, elements, attributes must have my student ID at the end like Order 09F4972.
